Answer 1

I face this problem this fix it to me

1. use attribute [JsonProperty("property name as in json request")] in your model by nuget package newton
2. if you serializeobject call PostAsync only

like that

var json = JsonConvert.SerializeObject(yourobject);
var stringContent = new StringContent(json, UnicodeEncoding.UTF8, "application/json");
var response = await client.PostAsync ("apiURL", stringContent);

3. if not work remove [from body] from your api
